2005 CADILLAC CTS ECU

Keep the original transmitter for use in other vehicles as
well as for future HomeLink®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
Internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Programming HomeLink®
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
HomeLink
®buttons while keeping the indicator light
in view.
3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
®button is pressed and
released.
To program the remaining two HomeLink
®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.

Convenience Net
The convenience net attaches to the oor and back wall
of the trunk using four anchor points allowing for two
positions. The net can be attached like a hammock
or anchored to lay at across the oor of the trunk. Put
small loads, like grocery bags, behind the net. It can
help keep them from falling over during sharp turns or
quick starts and stops.
The net is not for larger, heavier loads. Store them in the
trunk as far forward as you can. When not using the net,
hook the net to the tabs securing it to the sill plate.
Sunroof
Your vehicle may have a power sunroof. It will operate
when the ignition is turned on, or in accessory, or
when Retained Accessory Power (RAP) is active. See
Retained Accessory Power (RAP) on page 2-24The sunroof controls are
located on the overhead
console.
@(Half Open):Turn the control clockwise to this
position to open the glass panel half way. The sunshade
will open with the glass panel, or it can be opened
manually.
P(Comfort Stop):Turn the control clockwise to
this position to open the glass panel about three
quarters of the way open. The sunshade will open with
the glass panel, or it can be opened manually.
This is called the comfort stop position. It provides less
wind noise than the full-open position.
A(Full Open):Turn the control clockwise to this
position to open the glass panel all the way. The
sunshade will open with the glass panel, or it can be
opened manually.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency supplies in
your trunk.
Also seeTires on page 5-54.Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some winter
outer clothing, a small shovel, a ashlight, a red
cloth, and a couple of reective warning triangles. And,
if you will be driving under severe conditions, include
a small bag of sand, a piece of old carpet, or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
4-28

If you put things inside your vehicle, like suitcases,
tools, packages, or anything else, they will go as fast as
the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
Towing
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Service on page 7-5.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see Recreational Vehicle Towing following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your vehicle
with all four wheels on the ground) and “dolly towing”
(towing your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.

Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and then
apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
